SHORE CLAMP.

Application filed October 18, 1928. Serial No. 142,426.

This invention relates to certain novel improvements in shore clamps andhas for its principal object the provision of an improved constructionof this character which will be highly efiicient in use and economicalin manufacture.

Among the several objects of the invention is the provision of a deviceof this character which will be positive in its operation and performits duty with an assurance of safety.

A further object of the invention is the provision of a device of thischaracter which can be manually forced into clamping relation with shoresupporting bars for holding the bars in the required adjusted positionand one which can not be easily thrown from operative position byobjects striking thereupon or against.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of partsto be hereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings and in which:

Figs. 1 to 3 inclusive are detail views of the invention illustratingthe same in vari ous applied positions,

F ig. 4 is a sectional detail view of the invention taken substantiallyon line 4-4 of Fig. 1.

Fig. 5 is a sectional detail view taken substantially online 55 of Fig.1,

Fig. 6 is a plan view of one of the clamping elements embodied in theinvention, and

Fig. 7 is a perspective view of another of the clamping elementsembodied in the invention.

In the drawing 10 and 11 indicate two shore supporting bars which areadapted to be clamped in an adjusted position by means of my improvedshore clamp generally indicated at 12. My improved shore clamp includesclampingelements 13 and 14. The clamping element 13 is substantially Lshaped in plan view and has a bight portion 15 provided with an inneredge 16 forming a plurality of equally spaced apart teeth 17. Theseteeth 17 have their under surfaces 18 beveled in an inwardly andupwardly direction for reasons hereinafter set forth. The limb portions19 and 20 of this clamping element have their end portions bent uponthemselves to provide hook-shaped elements 21- The clamping element 1 1has depending portions 22 which provide guiding elements when theclamping element 1 1 is disposed transversely of the clamping element13, these guiding elements are adapted to embrace the outer edgeportions of the limb portions 13 contiguous the hook-shaped ends 21. Asshown in Fig. 7 the clamping element 11 has an edge portion 23 whichprovides a plurality of equally spaced apart teeth These teeth 21- havetheir top surfaces 25 beveled inwardly and downwardly for reasonshereinafter set forth. The clamping element 1 1 is adapted to bepositioned transversely of the clamping element 3 beneath thehook-shaped end portions 21 and when the clamping element 1 1 is inclamping position it is detachably latched from detachment with theclamping element 13 by a suitable latch 26. This latch 26 is pivotallyconnected to the limb portion 19 and provides an end portion 27 which issubstantially U-sha-ped in cross section to embrace adjacent portions ofthe limb portion 19 of the clamping element 14:.

In applying the clamping device in clamping position the bars 10 and 11are adjusted in the desired position and after this has beenaccomplished the clamping element 13 is disposed to embrace the bars 10and 11 in substantially the position illustrated in Figs. 1 to 3inclusive. When the clamping element 13 is in this position the clampingelement 14 is arranged in its proper position with respect to the limbportions 19 and 20. In these positions it will be noted, Fig. 3, thatthe teeth 17 and 24; are in position to bite into the adjacent surfacesof the shore supporting bars 10 and 11. The next step in applying myshore clamp is to draw the clamping elements so as to dispose theclamping element- 14: in applied position upon the limb portions 19 and20, it being pointed out that the hook-shaped end portions 21 serve as apivot for the clamping element 1 which is drawn into clamping re lationin the following manner.

A suitable tool is provided which includes handle portion 28 and thishandle portion 28 has an end portion 29 which is bifurcated as at 30.This bifurcated end portion is adapted to receive the body portion 31 ofthe clamping element 14-. When the tool is in the applied position shownin Fig. 2 it is manually drawn upwardly so as to pivot the clampingelement 14 within the confines of the hook-shape end portions 21. "hispivotal movement draws the clamping element 13 into position to disposethe clamping element 14: flatly upon adjaeentgportiens the limb portions19 and 20, it being pointed out that the hook.sl1ape end portions 21function further to prevent CllSPlCtCQlIlQTlll of the clamping elementhen the clamping element 14 has been drawn tightly into clampingposition it will be noted that the teeth 1'? and 2 l'will bite intoadjacent surfaces of the bars '10 and 11 thus preventing relativemovement of the shore clamp with respect to the bars 10 and 11. As willbe noted in Fig. 1 the bevelled surfaces 18 of the teeth 17 extend in aplane opposite the plane in which the bevelled surfaces 25 of theteethfle extend and thisresul'ts in that fact that if an object shouldstrike upon the clamping element 14; itwill tend to dig the teeth'furtherin'to the adjacent surfaces of the shore clamp rather thandisplace the clamping element from clamping position with respect toeach other.

VVhen the clamping elements are in clampinjg position the latch i ti isbrought into operation and functions to detachably latch the 'ela'mpinelements together.

VV'hile I have illustratedand descrihedthe preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification, without departing from the spirit of'theinvention. I,

neeeeee therefore do not wish to be limited to the precise details ofconstruction set forth, but desire to avail myself of such variationsand modifications as come within the scope of the appended claim.

The invention having; been set forth, what I claim as new and desire tosecure by Letters P'ZItGHt is A shore clamp including a clamping elementhaving one edge portion provided-with teeth and oppositely disaosedoutwardly extending portions at the ends of said element terminating indownwardly ;protruding portions, and a cooperating clamping elementformed substantially U-shapednnd having; an edge portion pm led withteeth'a'nd having portions provi mg a pivot for the first mentionedclamping; eleniei'it, said downwardly protruding portions on said firstmentioned clam nng element engaging said second mentioned clampingelement adjacent said pivot to limit transverse movement of saidfirst'men't ioned element, said outwardly extendingportions:beingadapted tobe disposed on opposite sides of saidcooperating;- clamping element, and a locking member 'pivotally mountedon one leg of said U-shapedmember and having a bifurcated portionadapted tobe disposedito loel: sa d clamping elements in clamping position.
